HallStar Co. has introduced a low-polarity polymer modifier for thermoplastic polyolefins, thermoplastic elastomers and similar polymers.
The Chicago-based company said RX 13804 is highly compatible with target polymers. It reduces the glass transition temperature of various plastics to give better low-temperature properties. Soft feel and handling also are improved, the firm claims. Typical usage levels are 5- 30 parts per hundred and the product can be processed over a wide temperature range.
